Weigh your rubbish

After finishing the clean up, first weigh your total rubbish collected as a team and record the weight below.

How to sort your rubbish

First, sort your rubbish into piles based on the following materials: (make sure to wear gloves and be careful of hazardous materials)

• Plastic
• Polystyrene/foam
• Glass & Ceramic
• Cloth
• Metal
• Paper & Cardboard
• Rubber
• Wood
• Other

How to organise items

Now that you've grouped your rubbish by material. You are going to organise all of the plastic items into piles representing the categories below.

After that, you're going to count and record the total number of each item. It's best to first group everything in to piles and then count.

There will be items that don't seem to fit any category. If you get stuck, choose the category that is most similar.

See bottom of page for a guide on how to calculate large quantities of items.

How to estimate large numbers of items

1. Separate out all the larger pieces and count them.
2. Divide the remaining smaller pieces into a number of equal sized blocks or piles and count one of those piles.
3. Multiply the result from step 2 by the total number of blocks or piles to give the estimated total of the smaller pieces.
4. Add the totals from steps 1 and 3 and record it on the Data Collection Sheet together with a note indicating the total is estimated.

Polystyrene
/Foam

Just like you did before with the plastic items, now do the same with the polystyrene/foam items.

Throughout this whole process, there will continue to be items that don't seem to fit any category. If you get stuck, choose the category that is most similar.

Other Materials

You know the drill now, we are going to follow the same process with the remaining materials.
